Title: Controller for winder turret
Inventor: YAGI TOMOJI
IPC: H02P5/46
Filed: 1995-03-07
Abstract: PURPOSE: To realize a wider turret operating as low as possible by disposing a speed detector on the prestage of a reservoir, inputting the feeding speed of a sheet material being fed to the reservoir along with the allowable stock to a turret speed setter, and delivering a turret speed command to a turret arm controller. CONSTITUTION: A speed detector 11 disposed on the prestage of a reservoir 6 detects the speed of a sheet material 1 being fed thereto and delivers a signal corresponding to the speed. A reservoir allowable capacity calculation circuit 12 calculates the quantity to be stocked in the reservoir 6 based on the output signal from a reservoir position detector 10 coupled directly with the reservoir 6 and outputs the quantity thus calculated. A turret speed setting circuit 13 receives the feeding speed from the speed detector 11 and the allowable stock from the reservoir allowable capacity calculation circuit 12 and delivers a turret speed command to a turret arm controller 9.

Title: Antenna
Inventor: MATSUMOTO WATARU
IPC: H01Q9/18
Filed: 1995-03-07
Abstract: PURPOSE: To manufacture an antenna by means of inexpensive thin film forming processing with high precision, stable quality and high reliability by forming the antenna with a thin film conductor onto a dielectric board. CONSTITUTION: A microstrip line 7 including a feeder line made of a thin film conductor, a couple of dipole antenna elements 6, a dipole antenna feeding slot 12, and a notch 8 whose electric length is 1/4 wavelength are provided onto a dielectric board. A signal fed to the microstrip line 7a being a feeder is electromagnetically coupled at a dipole feeder slot with the dipole antenna element, from which the signal is emitted as a radio wave. The matching is taken by adjusting a length (a) of the microstrip line 7 or by means of a matching circuit 11 having distributed constants. Since the antenna is made up of the dielectric board, excellent precision in the dimension is attained and the adjustment is easily taken by cutting off its pattern.

Title: Phase locked loop
Inventor: ITO TAKEO
IPC: H03L7/08
Filed: 1991-03-13
Abstract: PURPOSE:To prevent the phase of an output pulse from being changed even when the duty ratio of an input pulse is changed by providing a control circuit to keep the duty ratio of the input pulse constant. CONSTITUTION:Between the input terminal of an input pulse Pi and the input terminal of an R-S flip-flop C, a duty ratio control circuit D is provided to keep the duty ratio of the input pulse constant. In addition to the above- mentioned constitution, an error detection circuit E is provided to generate a control output corresponding to the output pulse width of the flip-flop C. Namely, since the input pulse Pi is inputted to the R-S flip-flop C after fixing the duty ratio, the output of the R-S flip-flop C does not generate the change of a direct current component caused by changing the duty ratio of the input pulse. Therefore, there is no influence in the phase of an output from a voltage controlled oscillator 0, namely, from the PLL circuit.
